Quantum Science Audio light blue fuse; $71, what a bargain!


I wanted to start a new thread about the more affordable versions of these fuses. I don’t doubt that the higher end versions are amazing, but most of us aren’t very likely to be able to hear them for ourselves. Fortunately, pretty much anyone who is serious about building a musically enjoyable and engaging system can get a good taste of what they’re all about.


I’ve had the light blue QSA fuses ($71) in my CD transport and DAC for over two weeks, now. They replaced SR blue fuses, at around twice the price, and easily bettered them. I am expecting one more light blue tomorrow, to replace an SR orange in my amp. I’ll give an update on that, once I get it installed and listen.


Meanwhile, here are a couple quotes from my posts on the other thread:


“What I am hearing is; voices & instruments are more solid and lifelike, with increased natural detail and sense of space, better dynamics, and a more relaxed overall sound.”


“Just got in a second light blue fuse for my DAC. So far, more of the same improvements I got in my CD transport. Very nice!😃 One thing I appreciate is the break in seems to be pretty quick, without any of the nasties you get with some other stuff. Pop it in, and you’ll hear improvements in short order, at least that’s been my experience.”


I am continuing to greatly enjoy what these fuses bring to my system, and am really looking forward to getting the last one in my amp.

jafant,

My modest CD based system currently consists of the following:


audiolab 8000CDM CD transport

Audio Note DAC Kit 1.1 NOS tube DAC

Antique Sound Lab T1 passive autoformer preamp

Antique Sound Lab Tulip stereo 2A3 SET amp

Audio Note AN-E-L speakers


These components are supported by numerous accessories, tweaks and mods, that I have found essential to getting the best out of them over the years. I am always looking for new ways to improve their performance.


My goal is to get as much of the life, energy, engagement and enjoyment, that I find in live music, out of my CD collection as possible. My musical tastes cover a wide variety of genres; rock, pop, classical, classic jazz, folk, classic country, bluegrass, Christian, Irish, Celtic et al. Basically, good music is good music, regardless of the style.


In my pursuit of enjoyment from home audio, I refuse to have my world made smaller by those that reject, and ridicule, anything they can’t understand, explain, or measure.

You're pretty new here, welcome.
You've certainly got the idea.
I'm afraid you can't tell the dum dums anything.
But you could get into selling gold fuses at $300 a pop?
